A Cymek Titan is a central figure in the Dune universe's pre-Butlerian Jihad era. It is a human brain encased in a liquid-filled container, integrated into a massive, highly advanced mechanical body. This fusion of human intellect with machine strength allows the Titan near-immortality, immense power, and control over vast armies. Equipped with tentacle-like actuators and an array of deadly weaponry, Cymek Titans are both warlords and tools of oppression, embodying the hubris of humanity's reliance on artificial intelligence and cybernetic enhancements before the rise of the anti-AI Butlerian Jihad.
